Simple Answer:
When the driving force for convection is removed, the system will return to thermal equilibrium.
Explanation:
If convection exists in a fluid because a heat source is maintaining a temperature gradient and then that heat source is removed, the fluid will return to a stationary state with uniform temperature in a sequence of three overlapping stages.
1. With no driving force, the system initially continues the current flow and transport of heat, but the flow will slow and cease due to internal fluid viscosity
2. When system inertia of initial flow dissipates, new convection forces develop due to remaining thermal gradients and push fluid towards a configuration where density profile are perpendicular to gravitational forces.
3. Existing temperature gradients in the fluid will diminish through thermal conduction as the system proceeds toward a final uniform temperature.

What provides the thermal energy for currents to be formed?
Thermal energy from the sun is the primary driver for the formation of ocean currents. The sun's heat causes water to expand and rise at the equator, creating warm surface currents. As the water moves towards the poles and cools, it becomes denser and sinks, completing the cycle of ocean circulation.
How is convention different from conduction?
Convention is the transfer of heat through fluid motion, such as air or water currents, while conduction is the transfer of heat within a material through direct contact. Convention relies on the movement of fluid to transfer heat, while conduction occurs through the vibrating molecules in a material.
What two spheres interact with wave currents?
The atmosphere and hydrosphere interact with wave currents. Wave currents are formed by the interactions of wind with the surface of the ocean, which is part of the hydrosphere, while the atmosphere plays a crucial role in generating and sustaining these wind patterns.
What three processes or forces combine to set convention currents in motion?
Unequal heating of Earth's surface: Differential heating of the Earth's surface by the sun creates temperature and pressure differences that drive convection currents. Rotation of Earth (Coriolis effect): The rotation of the Earth causes moving air or water to be deflected, which influences the direction of convection currents. Gravitational force: Gravity plays a role in pulling denser, cooler air or water downwards, while lighter, warmer air or water rises, initiating convection currents.
What are Currents powered by wind called?
Currents powered by wind are called wind-driven currents or wind-driven circulation. These currents are created by the friction between the wind and the surface of the water, causing the water to move in the direction of the wind.
Describe the similarities and differences between gyres and currents?
A difference between gyres and currents is that currents are formed by the wind, but gyres are formed by currents.
What is the heat source for earth's convention currents?
The sun.
How are suface currents formed?
from winds :)
Where are convection currents formed?
the ocean .
How are different type of currents formed?
normal
How far ahead of the date of a convention should committees be formed?
Normally, committees should be formed one year prior to the date of a convention.
What is a political convention?
A political convention consists of a meeting formed by a party. The goal of the convention is to pick candidates who will run for the party.
What cause convention currents in mantle?
the heat in the core raises and heat raises to a cold spot. so the convection currents raises to the surface of the earth.
What Surface ocean currents are primarily formed by?
winds
How do you describe convention currents by the ocean?
changing in heat in the ocean colder sinks warmer floats
How in toaster convection currents are formed?
Sponge bob has nothing to do with it.
How are convective currents formed?
From the uneven heating of the earths surface
